I am making a bootstrap website, with a couple of Bootstrap 'Modals'. I'm trying to customize some of the default features.

Problem is this; You can close the modal by clicking on the background. Is there anyway to disable this feature? On specifc modals only?

On Options chapter, in the page you linked, you can see the backdrop option. Passing this option with value 'static' will prevent closing the modal.
As @PedroVagner pointed on comments, you also can pass {keyboard: false} to prevent closing the modal by pressing Esc.

If you opening the modal by js use:

$('#myModal').modal({backdrop: 'static', keyboard: false})

If you are using data attributes, use:

 <button data-target="#myModal" data-toggle="modal" data-backdrop="static" data-keyboard="false">
    Launch demo modal
 </button>`

This is the easiest one

You can define your modal behavior, defining data-keyboard and data-backdrop.

<div id="modal" class="modal hide fade in" data-keyboard="false" data-backdrop="static">

You can use an attribute like this: data-backdrop="static" or with javascript:

$('#myModal').modal({
    backdrop: 'static',
    keyboard: false  // to prevent closing with Esc button (if you want this too)
})

In my application, I am using the below piece of code to show Bootstrap modal via jQuery.

 $('#myModall').modal({
                        backdrop: 'static',
                        keyboard: true, 
                        show: true
                });

You can use

$.fn.modal.prototype.constructor.Constructor.DEFAULTS.backdrop = 'static';
$.fn.modal.prototype.constructor.Constructor.DEFAULTS.keyboard =  false;

to change the default behavior.

There are two ways to disable click outside of bootstrap model area to close modal-

using javascript

$('#myModal').modal({
   backdrop: 'static',
   keyboard: false
});

using data attribute in HTML tag

data-backdrop="static" data-keyboard="false" //write this attributes in that button where you click to open the modal popup.

Checkout This ::

$(document).ready(function() {
    $("#popup").modal({
        show: false,
        backdrop: 'static'
    });
    
    $("#click-me").click(function() {
       $("#popup").modal("show");             
    });
});

        <script type="text/javascript" src="//netdna.bootstrapcdn.com/twitter-bootstrap/2.1.0/js/bootstrap.min.js"></script>
</html>

The solution that work for me is the following:

$('#myModal').modal({backdrop: 'static', keyboard: false})

backdrop: disabled the click outside event

keyboard: disabled the scape keyword event

Another option if you do not know if the modal has already been opened or not yet and you need to configure the modal options:

Bootstrap 3.4

var $modal = $('#modal');
var keyboard = false; // Prevent to close by ESC
var backdrop = 'static'; // Prevent to close on click outside the modal

if(typeof $modal.data('bs.modal') === 'undefined') { // Modal did not open yet
    $modal.modal({
        keyboard: keyboard,
        backdrop: backdrop
    });
} else { // Modal has already been opened
    $modal.data('bs.modal').options.keyboard = keyboard;
    $modal.data('bs.modal').options.backdrop = backdrop;

    if(keyboard === false) { 
        $modal.off('keydown.dismiss.bs.modal'); // Disable ESC
    } else { // 
        $modal.data('bs.modal').escape(); // Resets ESC
    }
}

Bootstrap 4.3+

var $modal = $('#modal');
var keyboard = false; // Prevent to close by ESC
var backdrop = 'static'; // Prevent to close on click outside the modal

if(typeof $modal.data('bs.modal') === 'undefined') { // Modal did not open yet
    $modal.modal({
        keyboard: keyboard,
        backdrop: backdrop
    });
} else { // Modal has already been opened
    $modal.data('bs.modal')._config.keyboard = keyboard;
    $modal.data('bs.modal')._config.backdrop = backdrop;

    if(keyboard === false) { 
        $modal.off('keydown.dismiss.bs.modal'); // Disable ESC
    } else { // 
        $modal.data('bs.modal').escape(); // Resets ESC
    }
}

Change options to _config

TLDR

backdrop: 'static'

https://getbootstrap.com/docs/3.3/javascript/#modals-options

specify static for a backdrop which doesn't close the modal on click.

You can Disallow closing of #signUp (This should be the id of the modal) modal when clicking outside of modal.
As well as on ESC button.
jQuery('#signUp').on('shown.bs.modal', function() {
    jQuery(this).data('bs.modal').options.backdrop = 'static';// For outside click of modal.
    jQuery(this).data('bs.modal').options.keyboard = false;// For ESC button.
})

Vijay Chauhan

Try this:

<div
  class="modal fade"
  id="customer_bill_gen"
  data-keyboard="false"
  data-backdrop="static"
>

You can also do this without using JQuery, like so:

<div id="myModal">

var modal = document.getElementById('myModal');
modal.backdrop = "static";
modal.keyboard = false;

Add the below css as per you want your screen width.

@media (min-width: 991px){
    .modal-dialog {
        margin: 0px 179px !important;
    }
}
